Planting & Care of Bulbs: After Blooming
Flowers should be removed when petals begin to fade, so they will not go to seed. If seed pods are allowed to remain, they will draw off the food needed to nourish your bulbs for next year’s growth. All petals should be removed from the blooming area after they have fallen. Even where bulbs have been naturalized in a lawn, leaves should not be cut until they turn yellow and whither naturally. While they are still green, the leaves serve as a source of nourishment to the bulbs.
